Lab Report Using Sciccor Leaves

The materials needed for this project were containers, leaves, light source and light blocker. Also needed for this lab is a syringe, sodium bicarbonate, water and a hole punch. The procedure for the lab was first to cut holes in the leaves to get little leaves to test the lab. Then you will fill 2 cups with about 150ml of water. Mix

1. Weigh five grams seaweed. 2. Wash the seaweed to get rid of Monosodium Glutamate 3. Boil the seaweed in 40 ml water for 5 minutes 4. Filter the seaweed and collect about 3 ml solution 5. Pour the solution to a clean beaker, then add 3 crystals of iodine 6. After 10 minutes, conduct the observation test

The plants have to be water, have sunlight and good soil. So what if we change it. Not the soil. Neither the amount of sunlight, but the water. We all know plants need water to survive. So if we change it what will happen? My experiment will show those result. I will use multiple things. Water, milk, soda (Pepsi) same soil from the same bag, same plant. I will get six plants in total. Two plants for each liquid. Every week for 5 weeks I will take a picture to record the result

To start off the experiment, materials were gathered and placed on the table, those materials were 6 different essential oils. Peppermint, lavender, sweet orange, tea tree, lemon and eucalyptus were all used in the experiment. After collecting the materials, the containers were labeled with the name of each essential oil and the agar was then heated using the microwave until it turned into liquid. The agar was then placed in the six different petri dishes and add three drops of each of the essential oil to its labeled petri dish. After the agar had solidified and cooled down it was placed in a room temperature and pictures were taken. Growth would be observed every two days by taking pictures and if growth is present, then the names of bacteria

In the first method it says we need a leaf, boiling water, alcohol, iodine, a beaker, and a heat source. First we put the leaf in the boiling water to soften the cell walls, next we put the leaf in a test tube and cover it with alcohol and place the test tube back in the boiling water, this removes the chlorophyll’s pigmentation, then we place the leaf on a petri dish and cover it in iodine. For the second method we feed the plant with radioactive carbon dioxide, The radioactive carbon atoms have become part of the structure of the plant. This shows that the plant absorbed the radioactive carbon.

The tube containing an Elodea densa plant, 100% red dye and no sodium bicarbonate solution resulted in an average pH level of 8.08. The tube containing no plant, 100% red dye, and no sodium bicarbonate solution resulted in an average pH level of 8.04. The tube containing 50% red dye, an Elodea densa plant, and 25mL of a sodium bicarbonate solution held an average pH level of 8.22, whereas the tube with 50%,no Elodea densa plant, and 25mL of a sodium bicarbonate solution produced an average pH level of 8.08.

Weakness and problems within the experiment we tested for could be that the pipet tip used in the experiment were not properly sterilised so there is a high possibility for contamination of the root and shoot. Also, This would not make it difficult to measure but will make the data less

The materials used in this lab were distilled water, a vase with Control solution, tap water in a plastic tray. Ag+ solutions with specific concentrations such as, 0.25 (Mm), 0.50 (Mm), 1.00 (Mm), 2.00(Mm), 4.00 (Mm), and AOA solutions with specific concentrations such as, 0.2 (Mm), 0.4 (Mm), 0.6 (Mm), 0.8 (Mm), and 1.0 (Mm), eleven carnations for each group and a razor blade and an electronic balance.

Note if any plants die. Checking the plants growth on an every 2 day bases. Step 6: On day 7 take the biomass of each each beaker, using a strainer to catch ALL plant material from the samples. Record the final appearance of the water samples. Subtract out the weight of the container holding the plants when weighed.

water, measure and observe the three plants. The independent variable in the experiment was the

At the beginning of the experiment, all the leaf discs sink at the bottom of beaker.As time

To begin the experiment all of the equipment was collected. This included a cake pan, Pasteur pipette, eye dropper with rubber bulb, 10 mL graduated cylinder, oleic acid, small test tube, lycopodium powder, glass plate, wax pencil, transfer paper, and scissors. To begin the cake pan was cleaned using distilled water and glassware soap. It is made sure that there is no residue left on the pan. Any residue left would have affected the results of the experiment. Next, the bulb was removed from the eye dropper and placed on the Pasteur pipette. Subsequently, the 10 mL graduated cylinder was filled with around 2mL of oleic acid, and the amount of oleic acid in the graduated cylinder was recorded as the initial volume. A small amount of oleic acid

The experiment which was conducted was to identify the effects of temperature of the beetroot discs. Majority of the pigment from the beetroot is found within the vacuole which is called anthocyanin and each of the vacuole is surrounded by a tonoplast membrane. Externally the cytoplasm is surrounded by the plasma membrane hence the foundation of the experiment depends on the temperature which will rapture the membrane and lead to a leakage of the pigment. The experiment consists of several different temperatures and same sized beetroot discs, the beetroot discs will be placed in 3 sets of discs in a tube test tube which will be placed in the distilled water in same test tube. Using a colorimeter once the beetroot have been exposed to the temperatures the colour of the distilled water will change therefore leaving a coloured water to be measured by a colorimeter, this is because the colorimeter measures the light being passed through the solution.

Purpose of Project The purpose of this project is to see if there is a difference in how plants grow based on what they are watered with. By watering five different plants with five different liquids and measuring them daily we will prove or disprove the hypothesis.

A starch test was completed on the leaves of each Elodea strand from each beaker.
